Area Forecast Discussion
National Weather Service Portland Oregon
352 AM PST Wed Nov 23 2016

.SYNOPSIS...An active weather pattern will bring periods of windy
conditions along the coast, valley rain and mountain snow for the
next several days. Heavy snow is expected in the South Washington
Cascades.  A frontal system will drop heavy rain along the coast and
in the coast range Thanksgiving day and evening.

&&

.SHORT TERM...Today through Friday...Cold air continues to move in
over the area this morning with Astoria and Troutdale wind
profiliers showing snow level around 3500 feet. Snow will continue
to fall in the Cascades this morning with another 2 or 3 inches
before noon. Snow will taper off this afternoon and mostly end by
evening. -30 deg C air will move over Southwest Washington and
Northwest Oregon interior this afternoon and model soundings show
some weak instability over the interior. There could be enough
sunbreaks this afternoon to initiate some thunderstorms and have
added a slight chance to the forecast for this afternoon in the
north.

The models are are a bit different this morning than yesterday with
the next front which will move to the coast tonight. The southeast
portion of our forecast area, including the Cascades of Lane County,
Foothills and southern Willamette valley remain out of the main
precipitation much longer as the next two systems approach. I have
lowered the PoPs and lessened the QPF in those areas. But...in the
north and along the coast and coast range it is a different story.
Warm front approaches S Washington N Oregon coast around midnight.
GFS is particularly strong with the warm front pushing up along the
Coast Range without making much inland progress Thursday morning.
ECMWF and NAM are also showing this tendency. The triple point
slides down the coast reaching Long Beach WA by mid day Thursday
then the front stalls. This is a significant change to the forecast
in that the baroclinic zone remains over the coast range for 12 to
18 hours, shifts a bit north Thursday evening before the next
stronger wave moves over the coast range Thursday night. The front
finally shifts south by Friday morning. The GFS goes pretty wild
with the QPF giving about 5 to 6.5 inches of precipitation to the
northern and central Coast Range in a little over 24 hours from
midnight Thursday through Friday morning. NAM and ECMWF also have
considerable rainfall but not as much. All this occurs without very
high precipitable water values remaining only around an inch. Water
vapor transport is not all that high either and this does not appear
to be an atmospheric river event, rather just a case of strong
frontogenesis along the baroclinic zone which does not move too much
during that period. I have raised the QPF for the Coast and Coast
Range and in the S Washington Cascades during that period. We will
have a better idea of what flooding threat this might bring later
this morning when we run through the hydrologic models with the new
precipitation forecast, but there will be more of a flooding threat
than we thought yesterday.

Snow levels will rise to 4500 feet Thursday as the next system moves
in with some warm advection from the south. There could be some cold
air trapped on the east side...especially in the north along the
mountains surrounding the upper Hood River Valley and in the South
Washington Cascades to keep the snow levels around 3500 feet as the
overrunning moisture moves in. Will continue the Winter Storm Watch
for the South Washington Cascades Thursday morning Thursday night as
the heavier precipitation moves.

Winds will increase along the coast this evening as the next system
approaches but the gradient remains somewhat easterly and winds may
not reach the coastal inland areas. We have changed the High Wind
Watch for the Coastal areas to a High Wind Warning for Beaches and
Headlands only in Oregon only. The stronger frontal wave moves in
Thursday afternoon through Thursday evening with high winds more
likely for the entire coast from southern washington to Central
coast of Oregon and will continue a High Wind Watch.

It appears wave energy reaching the coastline will be under high
surf advisory criteria for the upcoming large seas later tonight
and Thu.

By Friday all the models are showing less shower activity over much
of the forecast area but still likely in the south.
Schneider

.LONG TERM...(Friday night through Tuesday)...No Changes...Previous
Discussion from Tuesday afternoon below...The active weather
pattern will persist through the end of the forecast period as a
series of storm systems moves across the Pac NW. Models continue to
show an upper level trough dropping south out of the Gulf of Alaska
Friday night and moving inland Saturday which will keep unsettled
weather over the forecast area. Another trough looks to move across
the area Saturday night/Sunday, maintaining a showery pattern. It
will also bring snow levels down to around 2,500 to 3,000 ft late
Saturday through Sunday. With convective mixing with showers, could
see some snow bursts as low as around 2,000 ft but do not expect any
lasting accumulations that low. Showers will likely continue into
early next week under cool nw flow aloft but snow levels will bounce
back up to 3,000 to 4,000 ft through the rest of the forecast
period. Bowen

&&

.AVIATION...Showers continue to across the area today with
primarily VFR conditions with occasional MVFR CIGS or VIS through
midday. There will be a slight chance of thunderstorms for the
coastal TAF sites through this morning. The Cascades will remain
mostly obscured tonight and Wed. A warm front will bring
increasing steady rain to the coast this evening and conditions
should gradually deteriorate from VFR to low MVFR or possibly IFR
to the coast tonight. Most inland sites should remain VFR during
this time.

KPDX AND APPROACHES...Expect predominantly VFR with occasional
MVFR in heavier showers today. /mh

&&

.MARINE...Shower and a slight chance of thunderstorms today. The
next strong cold front moves across the waters from the NW
tonight into early Thu. Southerly winds will start to pick up
later Wed afternoon ahead of the front. Expect widespread gales
across the waters with this system by Wed evening. Seas increase
further with the front, reaching around 20 to 22 feet overnight
tonight into Thu morning.

Winds drop off from north to south behind the front Thursday
morning for a few hours until the next system approaches later
Thu. A surface low will form along the previous cold front and
lift it back northward as a warm front. Guidance still indicating
potential for storm force winds to develop so will continue with
the Storm Watch for Thu afternoon and evening. Current fcst is
for southerly winds 35 to 45 kt with gusts 50 to 55 kt. This
system will likely push seas toward the mid 20s Thu night.

Will see winds and seas start coming down on Friday as broad
troughing remains over the waters. Additional weaker fronts move
across the waters over the weekend, and seas may stay up around
10 to 15 ft. /mh
